Make one set of bridles to fit the furler and have the tack at the standard P19 height. I think I would make a second set of bridle wires so the jib tack is at the same height when not using the furler. Leave the forestay and pigtail alone.
If the lower forestay has a fork on the bottom, you can attach to the furler adjuster plate or a 7 hole adjuster when not using the drum.
